Definitions

  • the object of the present specification is a method for manufacturing an orthopaedic insole and the product thus obtained, whereby the upper part of said insole is geometrically transformed for the purpose of allowing its production by means of milling or additive manufacturing techniques.
  • an orthosis according to the definition of the International Organisation for Standardisation (ISO), is a support or another external device (apparatus) applied to the body for modifying functional or structural aspects of the neuromuscular and skeletal system.
  • ISO International Organisation for Standardisation
  • the term is used to refer to apparatuses or devices, splints, technical aids and supports used in orthopaedics, physiotherapy, and occupational therapy which correct or facilitate the performance of an action, activity, or movement, seeking to save energy and increase safety. They are used to hold, align, or correct deformities and to improve the function of the locomotor system.
  • Orthosis are different from prostheses as they do not partially or completely substitute an organ or limb with physical incapacity, disability, or dysmetry, but rather take over or reinforce its functions.
  • insoles which are elements placed inside shoes and used as an interface between feet and shoes, fall within said field, and the purpose of the insoles relates to the use thereof as a therapeutic measure in a plethora of pathologies ranging from the treatment of diabetes-associated neuropathies to the correction of dysmetries or the walking pattern.
  • the insoles perform their therapeutic action using two fundamental principles: redistribution of pressure and change in foot orientation in the different phases of walking.
  • the redistribution of pressure is carried out by means of adding elements to the upper part of the insole, such as metatarsal bars, subcalcaneal unweighting elements, fascial accommodations, etc.
  • elements such as metatarsal bars, subcalcaneal unweighting elements, fascial accommodations, etc.
  • the idea is that when there is a point on which a large amount of pressure is exerted while walking, that excessive pressure can be reduced by elevating other areas of the insole so that the area of contact of the foot increases or reducing the thickness in the area on which excessive pressure is exerted.
  • the change in the walking pattern is carried out by means of modifications in the orientation of the insole, changes in the height and geometry of the arch, or inclined planes in different areas which force the foot to have a different orientation.
  • the redistribution of pressure is performed by means of soft insoles or linings made of materials such as EVA to which modules or elements with specific shapes are incorporated.
  • the change in the walking pattern can also be performed in insoles manufactured entirely with flexible materials, although the use of rigid bases generally offers a better result.
  • an insole can be seen as a "sandwich" or multilayer structure having a rigid base that provides support and allows changing the orientation of the foot during the different phases of walking, and a soft surface on which treatments for the redistribution of pressure are performed.
  • insoles were conventionally performed by means of filling a mould of the patient's foot with plaster, subsequently modifying this mould, and performing series of material thermoforming and sanding steps.
  • This type of manufacturing technology is applicable both to rigid insoles, generally milled in materials such as polypropylene, and soft insoles, generally milled from blocks of materials such as EVA rubber.
  • patent ES 2 336 533 which describes a process for capturing the plantar image through a device with elastic membrane securing and tensioning means, as well as double-sided machining of the insole obtained in said process, the process being characterized by comprising the following steps:
  • patent ES 2 021 968 which describes an orthopaedic insole device for providing proper support for a patient's foot within a shoe, provided with a top surface for contacting the foot and a bottom surface for contacting a shoe insole, comprising: a shaped monolithic orthotic material formed in its top surface with a plurality of closely spaced, substantially parallel grooves whereby slippage of the foot relative to the orthotic device is controlled.
  • patent WO/2003/015670 describes an improved method of producing insoles that are used to correct foot deformities, comprising a sequence of process steps which begin with a prior diagnosis by a specialist, consisting of the examination of the feet in order to assess and, if the patient so requires, to correct the somatic deficiency thereof by means of surgery or by means of an orthotic insole after having obtained the diagnosis, in order to proceed to the production of the orthotic insole, characterised in that the method comprises:
  • this solution means that, while milling one side, given that it is a soft, non-rigid material, the other side may not be machined because the material, instead of being milled, is moved by the tool.
  • a (previously attempted) way for machining this soft part consists of sticking a block of soft material on an orthosis or rigid part for subsequent milling in a machine tool.
  • the lower surface of the soft part therefore takes the shape of the upper surface of the rigid part, and only the upper surface of the soft part has to be milled.
  • the technical problem solved by the present invention is to achieve an orthopaedic insole formed by a rigid base and a soft surface, incorporating a series of reliefs to perform redistributions of pressure while walking and allowing the production thereof by means of milling or additive manufacturing techniques, which allow mass manufacturing, reducing the cost for manufacturing and subsequently selling the obtained product (insole).
  • orthopaedic insoles or orthoses can be made by means of machinery present in the state of the art, eliminating the need to have a workshop with sanding and gluing systems and a stock of parts that do not allow making unweighting elements or surface changes for the redistribution of pressure.
  • sandwich-type orthopaedic insoles or orthoses can be manufactured within a shorter time with greater precision in element positioning as it allows using 3D modelling techniques that are only available when the insole is not made by means of sandwich-type method.
  • the method for manufacturing an orthopaedic insole comprises a first step 1 of 3D modelling a future insole with a specific geometry and which will ideally be formed by a soft surface 10 and a rigid surface 11.
  • the software uses mathematical models based on finite element and graph theories, where the structure of the flat upper flat is modelled, modelling a soft object the lower part of which is flat.
  • the method comprises a third step 3 for manufacturing the obtained soft surface 10a obtained in the second step 2 by means of milling or additive manufacturing techniques and a fourth step 4 of joining the obtained soft surface 10a to the rigid surface 11, obtaining a sandwich-type insole, as shown in Figure 3 .
  • the insole is formed by the soft surface or element 10 and the rigid surface or element 11 which are ideally designed as shown in Figure 2 .
  • the way to machine the original soft surface 10 is complicated as it has a curvature on top and another one at the bottom.
  • an obtained soft surface 10a which in turn contains a flat lower surface and is capable of obtaining a geometry identical to the geometry of the original soft surface 10 once said obtained soft surface 10a is joined to the rigid surface 11, bending and curving as it is formed from a soft material, as well as obtaining a geometry identical to the geometry of the original soft surface 10.
